iv hm inner mi of the pipe (KI-1i i3 mmmunicates with conduit M which is vertically seated on the surface of the wmmincr 5) min 0716 of its Sidfii fr-i iurim tn the engine. This confirmv 1 tends to near (aim upper and of the container 9 and has cmnmunicntion at or near said end with an air discharging pipu 15 whim is extended downwardly and rearwardly to' near the middle portion of the engine, and

8511/03 tn iiiualrsil ter held in said container will submerge and surround every portion of the said air cir- 'culating pipe or coil. The lower end of the conduit 14 is provided with a drain cock 19 to be used for the purpose of dischargin condensation that may accumulate in sai conduit.

Leading from the upper portion of the container or receptacle 9 and communicating with he cavity-of said receptacle above the line of the water level therein is a moisture conducting pipe 20 which is extended into the pipe 15 and by preference projected a slight distance into the pipe 15 at a point near its juncture with the upper portion of the conduit 14, and this moisture conducting pipe 20, is provided with a butter-fly valve 2 which may be manually operated so as to open or close said pipe, or to regulate the flow of moistened air therethrough. The pipe 15 is provided between the juncture of the pipe 20 therewith and its discharging end, with a relief or safety valve 22 of any well known construction, which is designed to automatically open should the pressure within the ipe 15 become excessive or abnormal. (iommunicating with the upper end of the pipe or coil 13 and extended through the wall of the receptacle 9 adjacent to the engine 8 is an air supply pipe 23 which leads to a blower casing 24 which blower andsaid casing is mounted on a suitably supported shaft 25, which shaft is geared to a driven shaft, such as the magneto shaft 26 of the machine. Communicating with the blower casing 24, is an air inta e pipe 27, the outer end of which is adapted for the intake of atmospheric air. This intake pi e 27 is provided with a throttle or butter-fi valve 28 and the pipe 2;; is provided with a similar valve 29 which valves are connected by means of links 30 and 31 so that they can be simultaneously operated or opened and closed. The link 31 uniting the upper end of the link 30 and the valve 29 has leading therefrom a suitably fulcrumed lever 32 to the upper end of which is connected an operating rod 33 which is extended through the dash board 6 as is clearly shown in Fig. 1 of the drawing. By reciprocating this rod in the proper direction it is obvious that the valves-28 and 29 can be moved so as toregulate the quantity of air forced throu h the pipe 23, coil 13 and pipe 15 which disc arges through the dome or flared enlargement 16 over or near the intake of the carbureter. In the present instance the shaft 25 of the blower 24 is shown as being provided with a pulley 34 over which is passed a belt 35 which also extends around a pulley 36 mounted on the driven or magneto shaft 26, which may be suitably supported and may be driven by means of suitable gearing, (not shown) operated by* the engine.

Communicating at one of itsends with the lower portion of the receptacle 9 is a pipe 37 which leads to a rotary pump 38 mounted on and operated by the driven or magneto shaft 26 which shaft may be equipped with a magneto 39 of the ordinary or any preferred construction. Leading from the pump casing 38 is a water supply pipe 40 which communicates through a pipe 41 and suitable connections with the water jacket of the engine 8' which water jacket has communication through pipe sections 42 with a return pipe 43 which communicates at one of its ends with the upper portion of the receptacle 9, by preference above the overflow pipe 12 thereof. Mounted on the dash board 6 is a receptacle 44 which is provided with a thermometer 45 to indicate the temperature of the water contained in the receptacle 44, and this receptacle has communication through extension pipes 46 and 47 with the pipes 41 and 43 respectively.

From the foregoing and by reference to the drawing, it will be readily understood and clearly seen, that by filling the tank or receptacle 9 with water until it overflows therefrom through the pipe 12, the coil or air conveying pipe 13 will be submerged and completely surrounded by the water in such a manner as to expose or subject the water to a large area or quantity of the air conveying pipe.

By applying power to the shaft 26 the pump 38 will be set in motion and through its instrumentality will draw water from the tank 9 through the pipe 37 to the pump casing and from thence through the ipes 40 and 41 to the water jacket of the engine from whence it will be forced by the pump, through the pipe sections 42 and return pipe 43 to the upper portion of the tank 9 into which it will be discharged from said pipe. In the operation of the shaft 26 the blower 24 will be operated which will cause air to be drawn through the intake pipe 27 into the blower casing and forced through the pipe 23 and from thence through the coil 13, conduit 14 and air outlet pipe 15, at the end of which latter pipe the air will be discharged near the intake of the carbureter. In this operation it is apparent that as fresh atmospheric air is continuously bein forced through the coil 13 the water in t e tank will be kept at a comparativel low temperature, and in such condition orced through the water jacket of the engine, by means of the pump, thus keeping the cylinders cool or at a reduced temperature.

In certain conditions of the atmosphere, it has been found that moist or humid air when supplied to the intake of the carbureter, is highly advantageous and increases the efficiency of the carbureter as well as the engine. To supply humid or moist air to the intake of the carbureter an auxiliary pipe 20 leading from the upper portion of the tank 9 and extended in to the upper portion of the pipe 15 is employed, so that when the air is forced through the coil 13, conduit 14 and pipe 15, it will by reason of the suction created as it passes the end of the pipe 20 Within the pipe 15, draw the moist air or steam from the upper portion of the tank 9 and discharge it at or near the intake of the carbureter. The relief valve 22 in the pipe 15 is used to provide an automatic vent for the air should the pressure thereof become too great in the pipe 15 while it is being forced therethrough.

From the above description of my invention it will be seen that the apparatus is of an extremely simple and comparatively inexpensive nature and is particularly Well adapted for use by reason of the material advantage attained by it in cooling or maintaining the engine cylinders at a reduced temperature and in supplying humid or moist air to the carbureter when desired, and it will also be seen from the above description that the apparatus is susceptible of considerable modification without material departure from the principles and spirt of the invention and for this reason I do not desire to be understood as limiting myself to the precise formation and arrangement of the several parts of the apparatus herein set forth in carrying out my invention in practice.

Having thus fully described my invention, what I claim as new and desire to se scure by Letters Patent is In an apparatus of the class described, the combination with a suitably mounted engine, of a carbureter having communication with the engine, a water container mounted near the engine, an air conveying pipe coil located in the container, a blower communicating with one end of said pipe coil, a discharge pipe in communication with the other end of sald coil and having its free end located near the intake of the carbureter, an auxiliary pipe leading from the upper portion of the container to and within said discharge pipe, means to regulate the passage of air through the intake to the blower and the discharge pipe therefrom as well as the auxiliary pipe, and means to operate the blower.
